DRIVING-BOX SHOE AND WEDGE. v

Application filed August 16, 1926. SeriaI No. 129,305.

My'invention relates to a new and useful improvement in a drivlng box shoe and wedge, adapted for use on locomotlvesand the like.

. .In the usefof. such shoes and wedges as now ,commonly manufactured, these parts are made from some cast metal whichv frequently fractures. while in use, thus necessistate.

. M It is an object of the presentinvention to vprovidea.shoeand wedge of th s class, in

theuseof which fractures will be eliminated and inwhich the expense in retaining these parts in satisfactory operativecondition will be reduced to a minimum. a

It is another object of the: invention; to provide a; shoe and wedgeof thisclass which --will be most efficient inoperatiomrendering the movement of the journal box n the ,Itlis, another object of the nprovide a'shoe and wedge of this class havfr,ame. less resisted and .making the riding of the vehicle smoother.

. ing a removal face madefrom comparatively soft material so that thewear on the journal and arrangement of oftime without replacement. I

Other objects will appear hereinafter.

Q The invention consistsinthe. combination parts herelnafter de scribed andjclaimed. T

which form a -stantially line 5i5 of Fig; 2.; 7

The invention will be best understood by a reference to the accompanying drawings part, of this specifieationand in} which,

Fig. 2 is a perspective view of a wedge embodying the invention. v j Fig. 3 is a plan view of the wear platef Fig. 4 is a plan view of the face of the Wedge with the wear plate'removed. a

Fig. 5 is.v a sectional view taken on subtatingvthe removaland replacement of the wentirepart while also lessening the safety ,of. travel; while beingused 1n a fractured j\ectingrib 11 having the incline face 11' lounted'between these ribs l0 and 11 is the journal box 12 which is adapted for vertical movement between the ribs when in use, this journal box serving as a journal for the. axle 13,'upon which the wheels 14; are mounted.

;;In the..drawings I-have illustrated indetailtheginvention applied to a wedge,but the inventionis equally adapted for use on a shoe, the structure and operation of. the invention being. substantially ,the ,same whether used on a wedge-.orused on a; shoe. .The wedge" comprises the main body 15 having an inclinetface adaptedfor 'engagement with the face 11' of the rib 11., Projectin'g outwardly from the sides of the body 1 5, are flanges '16 and 17 which embrace the 11'. Extending transversely of the wedge are tapered dove-tailed. grooves 18 and 1 9,

vthecorners 18 and 19 being l-roundedso that the presence of sharp edges, which .might chip offor; break, are. eliminated. This part of the wedgeit is preferred to form from; cast steel, so that a fracture of invention to .thewedge when in use becom s practically.

impossible; wear-,plate. 20. formed from a comparatively softfmateri'al, such as brass or the like..is provided on its outer face with the oil grooves 21 communicating with an opening 22.,- which projects 'through the j wear. plate and through the rib 23, which projects outwardly from the face of the plate 20. A similar rib-24 projects outward- ,ly from the same face of the plate,20' adjacentjtheopposite end. these ribs being/taperedyas clearly appears .in Fig. 3, and,

The invention is adapted for use. on- .-lo'comotives and similar vehicles in which a bol- Y adapted for engagement inthe grooves 18 and 19,.so. that the-wear plate 520 {may be very easily mountedon the wedge by-sliding vthe plate transversely of the wedge-the. smaller endsoftheribs 24 and 23 first engaging in the larger ends of the grooves 18 thewedge, so as to prevent-removal of the wear plate from the wedge proper; 1

. f .The struct'ure is such that the wear plate may bevv vervleasily and quickly, removed after ithas: .beenin use for some time on account of; lihlS ..II16thOd of attachmentyso that-sin .usef under-Lord inary conditions it will become necessary but to replace the Wear plate 20, the replacement of the wearplat-e 20 being a comparatively small cost to the cost of replacing the entire wedge. Formed in the wedge at opposite sides thereof are longitudinally extending openings 25 and 26 which coinmunicate with a transversely exforced, by a grease gun or other suitable means, upwardly into the passage 26 and outwardly into the lubricant, grooves 21, only very easlly and quickly had at all times; By

constructing the wedge in this manner, the wedge may be used for either right or left position, the innermost of the passages tion transmitted to the journal box because of its movements between the wedge and the shoe. r y

The shoe 29 illustrated in the drawings is constructed in a similar manner, this shoe 29 carrying the wear plate 20' provided with the ribs 23 and 24 which engage 'in the grooves. It is believed obvious that one skilled in'the art will readily recognize the structure of the shoe from a description of thestructure of the wedge and in the claims the reference to a wedge is intended to also embrace a shoe having'the same structure.

In the drawings I have shown the wedge provided with an opening 32 registering with the opening 31 formed. in the wear plate, these openings being usually openings formed in wedges of this class for the reception of the'binding shoulders which serve to' mount these wedges in operating positlons on' the ribs 11. W1th a wedge and shoe constructed in this manner the advan-' tages sought for are attained and a 'most eflicient device is provided;

WhileI have illustrated and described the prefer'red'form of my invention, I'do not wish to limit myself to the precise form of "structure shown, but desireto avail myself of such variations and modifications as may com-e'within the scope of the appended claimsl" f Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

" 1. A wedge of the class described comprising: a main body having transversely extending grooves on one face; a, wear plate; and ribs on said wear plate for engaging insaid grooves and attaching said wear plate proper lubrication of the wear plate may be grooves.

to said main body, said wear plate being detachable from said main body upon said engagement except upon transverse relative movement of said main body and saidwear plate. V r

2. A wedge of the class described comprising a main body having grooves formed on one of its faces, said grooves being tapered to provide a wider groove at one end than at the other; a'wear plate; transversely extending tapered ribs :onsaid wear each adapted for; engaging in one of said grooves for attaching said wear plate on saidmain body; the wear face of said wear plate hav ng'lubricant groves formed there-' in and passages extending in sald main body communicating with said grooves for affording a means of delivering lubricant to said grooves.

4. A wedge of the class describedcomprising, a main' body having transversely extending grooves formed in one of its faces,

said grooves being tapered to form one end wider than the other; a Wear plate of comparatively soft material; transversely ex tending tapered ribs on one of the faces of said wear plate, each adapted for engaging in one of said grooves for attachingsaid wear plate on said main body; said wear plate having on its wearingface, lubri-' cant grooves communicating'through 'suitable passages with a longitudinally extending passage formed at each side of'thle lower end of said main body; each of said longitudinally extending passages affording a means for delivering lubricant'toflsaid 5. A wedge of the class described comprising: a main body; detachablewear plate mounted on said main body,'said plate and said main body having passages formed therein for affording a me'ans of delivering lubricant th'rough'said passages to the wearing face of said wear plate, said-body having transversely extending grooves formed in one face; and means on said wear plate engaging in said grooves for retaining the passages in said plate and said main body in registration with each other.
